TELEGRAPHIC RECEIVING ORGANI-SMS.

Application filed July 25, 1914, Serial No. 853,080. 'Rencwed January 5,1917.

To all whom it may concern:

Be it known that 1, lemon zen of the United States, residing atPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in TelegraphicReceiving Organisms, of which the following is a specification.

My invention relates to an improvement in receiving telegraphicmessages.

Its object is to convert a series of vibratory pulses into onecontinuous signal.

It may be practised with simplex, duplex, diplex or quadruplex systems.

In the accompanying drawing I have illustrated the receiving arrangementof one terminal of a quadruplex system.

In this drawing, 1, 1 is the line of trans mission. 2 and 3 are the twoline relays adapted to receive positive and negative pulsesrespectively. Each of these relays is provided with a localized circuit,so as to convert the vibrations of the tongues of these relays into asignal with the aid of a sounder. As the arrangement of the localcircuit of relay 3 is a duplicate of the circuit of relay 2, I will onlydescribe the different parts and their functions as pertain- Krrsnn,citiing to relay 2. This relay is provided with the tongue 4 normallyresting at stop 5. The stop 6 is connected to battery 7 and primary 8 ofan inductorium, and through the same with tongue 4. 9 is a localizedrelay with the tongue 10 normally positioned between the stops 11 and12. The coil of this relay is connected to the secondary 13 of saidinductorium. Both of the stops 11 and 12 are connected together and withinterposition of the primary 1 1 and battery 15 to the tongue 10. 16 isa second localized relay provided with the two armatures 17 and 18 heldby their respective springs against the steps 19 and 20 respectively.These stops are connected together through wire 21. The coil of theelectro-magnet is connected to the secondary 22; 23 is a local circuitconnected with one of its terminals to the armature 17 and with itsother terminal to armature 18. In this circuit are in multiple the coilof sounder 2e and the battery 25.

The operation of this arrangement is as follows :Normally, the tongue ofrelay 2 Specification of Letters Patent.

rests against stop 5. It is supposed that this relay answers to positivepulses. As soon as positive pulses are transmitted from the far-offstation, the tongue a will vibrate and alternately connect with anddisconnect from stop 6. This contacting with stop 6 will generate in thesecondary 13 a pulse in one direction and the disconnecting with thisstop 6 will generate in the secondary a pulse of opposite direction. Therelay 9, being polarized and having a tongue normally standing betweenthe two stops, will throw its tongue through the first impulse to, say,the stop 11 and make contact therewith, and through the second impulsethe tongue will contact with the stop 12, and will then resume itsnormal position between these two contacts.

Through each contacting of the tongue with one or the other of the stopsa pulse will be generated in the secondary 22, so also will a pulse begenerated in the secondary 22 through the disconnecting of the tonguewith one or the other of the stops. These pulses will be successively ofopposite direction and they will in their turn energize the core of thepolarized relay 16 alternately with opposite polarities; the armatures17 and f8 will therefore be alternately and in succession drawn towardthe core and away from it, and will alternately and in successiondisconnect from their stopping point and again connect therewith. Thesevibrations will be in such succession that, as long as the pulses aregenerated in the secondary 22, the armature 17, after being drawn fromits stopping-point 19, will not connect again with its stopping-pointtill the armature 18 has been disconnected from its point 20, andtherefore battery 25, which is normally armatures, will have thisshort-circuit broken till the generation of the pulses in the secondaryceases. And as the battery 25 is free to exert its influence on thesounder 24 as long as the short-circuit is broken, it is obvious thatthe armature of the sounder will be drawn down and will stay down tillthese pulses cease. In other words, the vibratory movements of thetongue of the relay 2, due to a series of quick pulses will betranslated on the sounder in one down stroke, translating these pulsesinto one unbroken signal.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is 1.' In combination with a telegraphic line,means to receive signals impressed upon said line in combination withmeans to translate said signals comprising vibratory line relay, anelectric circuit therefor, a second relay, an inductorium, the primaryinserted in the circuit of the first relay and the secondary inserted inthe circuit of the second relay, a second localized relay operativelyrelated to said first localized relay and translating means operativelyrelated to said second 10- calized relay.

2. In a system of telegraphy, in which a series of pulses aretransmitted for each signal, a line relay, a vibratory tongue therefor,a local circuit comprising the primary of an inductorium and a source ofcurrent adapted to be made and broken through said vibratory tongue, alocalized relay connected to the secondary of said inductorium, acircuit comprising the primary of a second inductorium and a source ofcurrent therefor, a second localized relay connected to the secondary ofsaid second inductorium, a source of current and a sounder, said sourceof current normally shunted through the armature of said second relayand adapted to operate said sounder when the shunt is broken.

3. In combination with a telegraphic line, two vibratory relays in saidline, each of said vibratory relays provided with inductoriums andlocalized relays operatively related thereto and means to translate thevibrations of one or the other of the localized relays.

In testimony whereof I aiiix my signature in presence of two witnesses.
